CLASSIFICATION OF FUNGI. 57

 plants when they are succulent and composed 

 of juicy, cellular tissue. They do not become 

 leathery. In the genus Clavaria the fungi have 

 no caps, but they have stems. There are a few 

 edible species. One can scarcely walk any 

 distance without seeing some species of Cla- 

 varia. They are conspicuous, sometimes at- 

 tractive looking, and interesting in their 

 variety. 



The genus Cortinarius, one of the order of 

 Agarics, has been already described, but it 

 contains so many species that it deserves es- 

 pecial mention. 



They are difficult to define. The genus has 

 been subdivided by botanists into tribes which 

 it may be well to enumerate. We have fol- 

 lowed Stevenson's arrangement. 



He divides Cortinarius into six tribes. 



1. Phlegacium = clammy moisture. In this 

 tribe the cap is fleshy and sticky (viscous), 

 while the stem is firm and dry. In all Corti- 

 narii the gills become cinnamon-colored. There 

 are many large-sized mushrooms in this tribe,

 stem sticky (viscous), and the universal veil is
